    Wireless problem on Ubuntu 12.04 LTS (BCM 4313)

    I have an Acer Aspire AOD270 netbook with Broadcom Bcm4313 wireless card. I already installed the broadcom STA driver. But, my wifi can't connect to my netbook. Please help !

    Deactivate the Broadcom-STA driver, clean up the old config and install the missing firmware for the native driver:
    Code:
    wget http://media.cdn.ubuntu-de.org/forum/attachments/39/45/5007272-Broadcom_Firmware_fae7121.tar.gz
    sudo tar xvf 5007272-Broadcom_Firmware_fae7121.tar.gz -C /lib/firmware 
    sudo apt-get remove --purge bcmwl-kernel-source
    sudo rm /etc/modprobe.d/blacklist-bcm43.conf
    sudo rm /etc/modprobe.d/broadcom-sta-common.conf
    sudo rm /etc/modprobe.d/broadcom-sta-dkms.conf
    Reboot.

    There is no need to downgrade, can you connect via cable and use the commands named?
